Revert "ASoC: core: use component driver name as component name"
Using component driver as a name is not unique and it breaks audio in
certain configurations, e.g. Hardkernel Odroid XU3 board where following
components are registered:
 - "3830000.i2s" with driver name "snd_dmaengine_pcm"
 - "3830000.i2s-sec" with driver name "snd_dmaengine_pcm"
 - "3830000.i2s" with driver name "samsung-i2s"

This reverts commit b19671d6ca.

ASoC: Intel: use common helpers to detect CPUs
We have duplicated code in multiple locations (atom, machine drivers,
SOF) to detect Baytrail, Cherrytrail and other SOCs. This is not very
elegant, and introduces dependencies on CONFIG_X86 that prevent
COMPILE_TEST from working.

Add common helpers to provide same functionality in a cleaner
way. This will also help support the DMI-based quirks being introduced
to handle SOF/SST autodetection.

ASoC: SOF: force end-of-file for debugfs trace at suspend
Current trace implementation gets out of sync when sof device
is put to suspend. The debugfs file handle is kept open, but
firmware will reset its state. After resume, debugfs client's
read offset will not be synchronized to firmware and this may
result in traces read in incorrect order and/or stale data being
read after resume.

Add logic to signal end-of-file to read() when firmware tracing
has ended, and all trace data has been read. This allows debugfs
client to capture all trace data, and reopen the trace file to
ensure proper synchronization with firmware after reopening
the node.

ASoC: SOF: ipc: fix a race, leading to IPC timeouts
Currently on all supported platforms the IPC IRQ thread first signals
the sender when an IPC response is received from the DSP, then unmasks
the IPC interrupt. Those actions are performed without holding any
locks, so the thread can be interrupted between them. IPC timeouts
have been observed in such scenarios: if the sender is woken up and it
proceeds with sending the next message without unmasking the IPC
interrupt, it can miss the next response. This patch takes a spin-lock
to prevent the IRQ thread from being preempted at that point. It also
makes sure, that the next IPC transmission by the host cannot take
place before the IRQ thread has finished updating all the required IPC
registers.

In some configurations, it's a requirement to split the probe in two,
with a second part handled in a workqueue (e.g. for HDMI support
which depends on the DRM modules).

SOF already handles these configurations but the error flow is
incorrect. When an error occurs in the workqueue, the probe has
technically already completed. If we release the resources on errors,
this generates kernel oops/use-after-free when the resources are
released a second time on module removal.

ASoC: SOF: core: remove DSP after unregistering machine driver
snd_sof_remove() disables the DSP and unmaps the DSP BAR.
Removing topology after disabling the DSP results in a
kernel panic while unloading the pipeline widget. This is
because pipeline widget unload attempts to power down
the core it is scheduled on by accessing the DSP registers.

So, the suggested fix here is to unregister the machine driver
first to remove the topology and then disable the DSP
to avoid the situation described above.

Note that the kernel panic only happens in cases where the
HDaudio link is not managed by the hdac library,
e.g. no codec or when HDMI is not supported.
When the hdac library is used, snd_sof_remove() calls
snd_hdac_ext_bus_device_remove() to remove the codec which
unregisters the component driver thereby also removing the
topology before the DSP is disabled.

ASoC: soc-core: fixup references at soc_cleanup_card_resources()
commit 53e947a0e1 ("ASoC: soc-core: merge card resources cleanup
method") merged cleanup method of snd_soc_instantiate_card() and
soc_cleanup_card_resources().

But, after this commit, if user uses unbind/bind to Component factor
drivers, Kernel might indicates refcount error at
soc_cleanup_card_resources().

The 1st reason is card->snd_card is still exist even though
snd_card_free() was called, but it is already cleaned.
We need to set NULL to it.

2nd is card->dapm and card create debugfs, but its dentry is still
exist even though it was removed. We need to set NULL to it.

ASoC: simple-card: Restore original configuration of DAI format
Revert commit 069d037aea ("ASoC: simple-card: Fix configuration of
DAI format"). During further review, it turns out that the actual issue
was caused by an incorrectly formatted device-tree node describing the
soundcard.

The following is incorrect because the simple-audio-card
'bitclock-master' and 'frame-master' properties should not reference the
actual codec phandle ...

	sound {
		compatible = "simple-audio-card";
		...
	=>	simple-audio-card,bitclock-master = <&codec>;
	=>	simple-audio-card,frame-master = <&codec>;
		...

		simple-audio-card,cpu {
			sound-dai = <&xxx>;
		};

		simple-audio-card,codec {
	=>		sound-dai = <&codec>;
		};
	};

Rather, these properties should reference the phandle to the
'simple-audio-card,codec' property as shown below ...

	sound {
		compatible = "simple-audio-card";
		...
	=>	simple-audio-card,bitclock-master = <&codec>;
	=>	simple-audio-card,frame-master = <&codec>;
		...

		simple-audio-card,cpu {
			sound-dai = <&xxx>;
		};

	=>	codec: simple-audio-card,codec { /* simple-card wants here */
			sound-dai = <&xxx>;	 /* not here */
		};
	};

Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes, in particular in the
context in which this code is being used.

So, replace code of the following form:

sizeof(*fwk) + fwk->num_services * sizeof(fwk->svc_api_info[0]);

with:

struct_size(fwk, svc_api_info, fwk->num_services)

and so on...

Notice that variables bytes and len are unnecessary, hence they are
removed.

ASoC: dapm: Use struct_size() in krealloc()
One of the more common cases of allocation size calculations is finding the
size of a structure that has a zero-sized array at the end, along with
memory for some number of elements for that array. For example:

struct foo {
    int stuff;
    struct boo entry[];
};

instance = krealloc(instance, sizeof(struct foo) + count * sizeof(struct boo), GFP_KERNEL);

Instead of leaving these open-coded and prone to type mistakes, use the new
struct_size() helper:

instance = krealloc(instance, struct_size(instance, entry, count), GFP_KERNEL);

This code was detected with the help of Coccinelle.

Two options to fix:
1. add an extra return statement if devm_snd_soc_register_card()

2. move devm_snd_soc_register_card() to the end of probe

Adopt option 2 which is more clear and common.

ASoC: Intel: Add machine driver for CX2072X on BYT/CHT platforms
This is an implementation of a machine driver needed for Conexant
CX2072X codec on Intel Baytrail and Cherrytrail platforms.  The
current patch is based on the initial work by Pierre-Louis Bossart and
the other Intel machine drivers.

The jack detection support (driven via the standard GPIO) was added on
top of the original work.

Tested with ASUS E200HA laptop.

ASoC: Add support for Conexant CX2072X CODEC
Initial commit of the Conexant CX2072X CODEC driver. Some features are
not present.

The CX2072X is a ultra low power stereo audio codec supports I2S/TDM
host interface with EQ, DRC features in playback mode.

Featues of CX2072X codec:

 * Two 24 bits DACs and DACs.
 * Stereo Headphone AMP.
 * 2.8W per channel class-D output.
 * Integrated seven bands per channel EQ and DRC.
 * Fully integrated headset support with detect/switch.
 * Stereo digital microphone for array applications.
 * S/PDIF output.
 * Bi-directional GPIOs.
 * Support analog and digital PC Beeep.
 * One headset button support.
 * Supports a wide variety of host interfaces.
   -wide variety of I2S and similar bit-stream formats
    with word lengths of up to 24 bits.
   -TDM stream supports up to 4 channels.
 * AEC loopback support.

Further fixes by tiwai:
 * Rebase to 5.2+
 * Missing DAPM entry definitions
 * Missing power hooks
 * Fix uninitialized variable warning
 * Rewrite jack detection stuff to use set_jack callback
 * Plumbing jack detection code for Intel ASoC
 * Move clk management into runtime PM
 * Drop incorrect regcache usages
 * Drop untested stuff: OF table, EQ/DRC handling
 * Lots of code cleanups and minor refactoring

The OF code was dropped due to the lack of testability.
It should be easy to re-add once if someone can test it.

v2->v3: Move register tables to appropriate place
	Remove some confusing codes
	Set snd_ctl_boolean_* helpers directly
	Fix EQ put callback
	Rename to "DAC1 Switch" from "DAC1 Mute Switch"
	Drop superfluous regmap calls at shutdown
	Avoid regmap_register_patch()
	Add missing register definitions
	Fix register access on big-endian machine
	Remove regcache messes
v3->v4: Fix the wrong endianess conversion in reg write
	Minor code cleanups
v4->v5: Move clk management to runtime PM
	Sparse warning fixes
	Some more code simplification
	Drop tricky regcache fiddling
	Apply mutex locks around possible racy sequences
	Move exported jack detection stuff into set_jack callback
v5->v6: Drop buggy&untested EQ and DRC codes
	Lots of code reduction/cleanup
	Add more comments about platform-specific stuff
